## Introduction

Hermes is a 24/7 autonomous agent that lives on your computer or server — it remembers what it learns and evolves as your usage grows.
This guide explains the easiest and most robust way to connect your Exist account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either.

## TL;DR

### What is Composio Connect?
Composio Connect is a consumer offering that lets anyone plug 1,000+ applications directly into their agent harness — including Hermes. It can:
- Search and load tools from relevant toolkits on-demand, reducing context usage.
- Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM.
- Manage app authentication end-to-end with zero manual overhead.

## Connect Exist to Hermes

### Integrating Exist with Hermes
### Using Composio Connect CLI
1. Install the Composio CLI
Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you.

```bash
curl -fsSL https://composio.dev/install | bash
```

## What is the Exist MCP server, and what's possible with it?

The Exist MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Exist account. It provides structured and secure access to your personal analytics data, so your agent can perform actions like analyzing correlations, retrieving user attributes, exploring supported metrics, and inspecting your profile on your behalf.
- Personal profile access and insights: Instantly retrieve and review your Exist user profile, including preferences and account settings, to keep your agent aware of your context.
- Attribute exploration and discovery: Browse and list all available attribute templates or user attributes, making it easy to understand what metrics you can track, analyze, or visualize.
- Correlation analysis: Ask your agent to fetch and explore recent correlations between tracked attributes—like how weather or sleep might relate to your mood or productivity.
- Custom analytics setup: Let your agent help you discover and understand supported attribute templates before you start tracking or updating new data points.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `EXIST_EXIST_GET_USER_PROFILE` | Get User Profile | Tool to retrieve the authenticated user's profile details and preferences. use after authentication to inspect account settings and status. |
| `EXIST_EXIST_OAUTH2_AUTHORIZE` | Exist OAuth2 Authorize | Tool to initiate the oauth2 authorization flow for user consent. use when you need an authorization code before exchanging for an access token. |
| `EXIST_EXIST_OAUTH2_AUTHORIZE` | Exist OAuth2 Authorize | Tool to initiate the oauth2 authorization flow for user consent. use when you need to obtain an authorization code before exchanging for an access token. |
| `EXIST_GET_ATTRIBUTE_TEMPLATES` | Get Attribute Templates | Tool to retrieve a paged list of supported attribute templates. use when you need to browse available templates before creating or updating data. |
| `EXIST_GET_CORRELATIONS` | Get Correlations | Tool to retrieve a paginated list of recent correlations. use when exploring relationships between your tracked attributes, optionally filtering by strength or attribute. |
| `EXIST_GET_USER_ATTRIBUTES` | Get User Attributes | Tool to retrieve a paged list of the user's attributes without values. use when you need metadata on available attributes for filtering or selection. |
| `EXIST_EXIST_GET_USER_PROFILE` | Get User Profile | Tool to retrieve the authenticated user's profile details and preferences. use after authentication to inspect account settings and status. |

## Creating MCP Server - Stand-alone vs Composio SDK

The Exist MCP server provides comprehensive access to Exist operations through Composio. Once connected, Hermes can perform all major Exist actions on your behalf using natural language commands.

## Conclusion

### Way Forward
With Exist connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to.
From here, you can extend Hermes further:
- Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Hermes can do for you.
- Build workflows across tools: Once multiple apps are connected, Hermes can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft.
- Let it learn your patterns: The more you use Hermes, the better it gets at anticipating how you'd handle recurring tasks. Give it feedback on drafts and decisions, and it will adapt.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Exist MCP?

With a standalone Exist MCP server, the agents and LLMs can only access a fixed set of Exist tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Exist and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Hermes?

Yes, you can. Hermes fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Exist tools.

### Can I manage the permissions and scopes for Exist while using Tool Router?

Yes, absolutely. You can configure which Exist scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Exist data and credentials are handled as safely as possible.
